Description

Conveniently-implanted transradial coronary angiography catheter

Technical Field

The invention relates to the technical field of medical supplies, in particular to a conveniently implanted transradial coronary angiography catheter.

Background

The contrast catheter is a key device for percutaneous angiography, and has the advantages of appropriate hardness, elasticity, flexibility and torsion, good X-ray penetrating performance, good shape memory, smooth tube wall, high contrast performance and capability of controlling thrombosis performance in a minimum range. The radiography conduit is a long rubber tube and is mainly used for providing the conduit so that the contrast agent can be smoothly introduced into the blood vessel to generate the radiography effect. Therefore, a contrast catheter should have the following basic conditions: the smooth inner tube can generate high flow, the developing performance is high, the non-traumatic head end needs to have high performance of keeping original shape, is not easy to deform, can allow a guide wire to pass through easily and the like. However, the existing angiography catheter has low elastic strength, and meanwhile, the bending of the catheter body cannot be avoided, so that the convenient implantation type transradial coronary angiography catheter is provided for solving the problems.

Disclosure of Invention

The invention aims to provide a conveniently-implanted transradial coronary angiography catheter which has the advantages of high elastic strength and capability of avoiding bending of a catheter body, and solves the problems that the conventional angiography catheter is not high in elastic strength and cannot avoid bending of the catheter body.

In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a radial artery coronary angiography pipe convenient to implant, includes the body, the return bend is installed to one side of body, the connector is installed to the other end of return bend, the tube head is installed to the other end of connector, body and return bend include equal inner tube layer, the surface mounting of inner tube layer has the metal pipe layer, the surface mounting on metal pipe layer has metal mesh layer, the surface mounting on metal mesh layer has outer pipe layer.

Preferably, the other end of the tube body is provided with a handle, and the surface of the handle is integrally processed with a plurality of fins.

Preferably, the other end of the handle is provided with a plug, and a blocking pad is arranged inside the plug.

Preferably, the inner tube layer and the outer tube layer are both made of a flexible plastic material.

Preferably, the metal tube layer is made of an elastic stainless steel material.

Compared with the prior art, the invention has the following beneficial effects:

according to the invention, the pipe body is rotated to drive the bent pipe to rotate, and the elasticity of the device can be effectively enhanced through the arrangement of the metal pipe layer;

according to the invention, the metal mesh layer is arranged, so that the toughness of the device can be effectively enhanced, and the bending condition of the pipe body and the bent pipe can be effectively avoided.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, a conveniently implanted transradial coronary angiography catheter comprises a catheter body 1, wherein one side of the catheter body 1 is provided with an elbow pipe 2, the other end of the elbow pipe 2 is provided with a connector 3, the other end of the connector 3 is provided with a pipe head 4, the catheter body 1 and the elbow pipe 2 comprise an equal inner pipe layer 5, the surface of the inner pipe layer 5 is provided with a metal pipe layer 6, the surface of the metal pipe layer 6 is provided with a metal mesh layer 7, and the surface of the metal mesh layer 7 is provided with an outer pipe layer 8.

Further, handle 9 is installed to the other end of body 1, and handle 9's surperficial integrated into one piece has a plurality of fin, through setting up the fin, can the person of facilitating the use operate handle 9.

Furthermore, a plug 10 is installed at the other end of the handle 9, a blocking pad is installed inside the plug 10, and air can be effectively blocked from entering the air-conditioning system by the aid of the blocking pad.

Furthermore, the inner pipe layer 5 and the outer pipe layer 8 are both made of flexible plastic materials, so that blood vessels can be effectively protected.

Furthermore, the metal tube layer 6 is made of elastic stainless steel materials, so that the elasticity of the device can be effectively enhanced.

The working principle is as follows: the user can be through rotating body 1, makes body 1 drive return bend 2 rotate, through the setting of metal tube layer 6 to can effectively strengthen the device's elasticity, simultaneously through setting up metal mesh layer 7, can effectively strengthen the device's toughness, thereby can effectively avoid the condition of buckling to appear in body 1 and return bend 2.
